You may find that the Weber has to be adjusted to make the most of the change
(or you may find that the Weber was set up assuming a header). Chris King's
advice to talk to Ted Schumacher first is sound particularly if you have a
Weber. He'll be able to advise you on the best combination of carb set-up,
header and exhaust and save you a lot of experimentation.
